Megger HVB10
The HVB10 is a highly accurate high voltage (HV) bridge designed to locate cable and sheath faults, perform sheath testing and fault finding. It is particularly suitable for long HV cables.
HVB 10 Special Benefits:
Automatic test sequences and only one connection cable
Bi-Polar Signigalization Technology for Elimination of Disorders
Very easy operation with one-button jog dial control and menus on large LCD screen
Very high sensitivity with 5 µv
USB Report Opportunity
Step tension method for cutting errors
Cutting Failing and Signing Localization Integrated
Detection and indication of incorrect connection
Integrated discharge up to 25 µf (ie can test very long cable lengths)
Integrated rechargeable battery
Power cables can have a cross section from 150 mm² to 1200 mm² and lengths can be from 500 meters up to a few hundred kilometers.
Maximum capacitance such as HVB 10 can recharge is 25µF @ 10 kv
→ Approximately 50 km @ 10 kv
→ Approximately 200 km @ 5 kv
The real cable capacitance is automatically measured and the equipment is adapted by limiting the output tensioner, if the cable capacitance exceeds the limit of 25µF. Ie The measurement bridge HVB 10 automatically reduces the voltage according to its ability to discharge the measuring object, which is 25µF. This means that you can measure about 50 km of cable at 10 kv and about 200km at 5kv. Depending on the cable structure of course.
